David Bailey (Dec 28 2023 at 20:23): David Bailey (Dec 28 2023 at 20:23):I have a silly question about GridSpec. I am trying to do a 3 panel plot with the third one in a second row, centered in the middle. When I do something like:
gs = GridSpec(2,2)
ax = fig.add_subplot(gs[0,0], ...)
ax = fig.add_subplot(gs[0,1], ...)
ax = fig.add_subplot(gs[1,:], ...)
The plot in the second row is right-aligned instead of centered. I can get it to work with GridSpec(3,3), but then I have a bunch of whitespace. What am I missing here?

Anissa Zacharias (Dec 28 2023 at 20:27):Hello Dave,
I think you might actually want to try subplot_mosaic if you're open to abandoning GridSpec.
See this example that has a very similar layout to what you're describing
Anissa Zacharias (Dec 28 2023 at 20:30):Here's a more general subplot_mosaic example , too . This is my preferred method to do anything with non-standard subplot layouts!
Fred Castruccio (Jan 02 2024 at 19:02):Hi Dave,
I think this is what you want.
fig = plt.figure(tight_layout=True)
gs = gridspec.GridSpec(2, 4)
ax1 = fig.add_subplot(gs[0, :2])
ax2 = fig.add_subplot(gs[0, 2:])
ax3 = fig.add_subplot(gs[1, 1:3])
Cheers,
Fred
